A scale-aware, runtime-enforced multi-agent governance mode for DeepSeek Harness.

English · 简体中文

Tang Governance

Tang Governance is an independent npm bundle that adds a Three Departments and Six Ministries development mode to DeepSeek Harness. It does not patch Harness source code.

The plugin turns a single coding request into an auditable workflow with requirement clarification, independent review, explicit user approval, responsibility-based execution, acceptance testing, and a user-controlled closure gate. Runtime checks enforce the important boundaries instead of relying on prompts alone.

Inspired by the Tang dynasty's administrative structure; designed for modern AI-agent software delivery.

Highlights

• Scale-aware intake — Zhongshu classifies the request as small, medium, or large and keeps simple tasks out of unnecessary full-process loops.
• Clarification before drafting — ambiguous requirements pause at a native choice interface before a solution is written.
• Independent review and countersignature — Menxia reviews the specification independently and may remand concrete issues.
• Explicit user gates — implementation cannot begin before approval; a case cannot close before final acceptance and user confirmation.
• Uniform ministry routing — Shangshu scans all six responsibility domains using the same rules, dispatching only the ministries that materially contribute.
• Runtime-enforced boundaries — delegation hierarchy, ministry roles, dependencies, verification, approval, and closure are validated by code.
• Observable execution — a responsive organization map, collapsible phase timeline, per-agent token usage, live status, and department records stay visible in one dashboard.
• Stable model inheritance — the Three Departments can be routed independently; the Six Ministries inherit Shangshu's provider and model while using task-appropriate reasoning effort.
• Durable case files — every task produces a structured dossier under .tang/cases/<case-id>/.
• Recoverable stop semantics — the user may stop work at any time without discarding completed artifacts.

Product tour

Native mode entry Select the governance mode directly from the Harness preset menu.	Organization map + live trace Department state, routing controls, real calls, phases, and token usage share one responsive view.
Clarify before planning Zhongshu asks task-specific questions before drafting when the original request is ambiguous.	Reviewable approval gate The countersigned Markdown proposal is rendered in a dedicated approval workspace.
Auditable department records Department cards expose chronological stages, evidence, and final status without leaving the dashboard.	User-controlled closure Acceptance evidence, artifacts, risks, and the chronicle remain reviewable before the case is closed.

Installation

Requirements:

• Node.js ^22.19.0 || >=24
• DeepSeek Harness 0.1.1-rc.2 or a compatible 0.1.x release

Install from a local checkout:

git clone https://github.com/Ruszero01/dsh-tang-governance.git
cd dsh-tang-governance
pnpm install
pnpm run check
dsh plugin --profile web add link:.
dsh web --no-open

Open http://127.0.0.1:3080 and select the mode for a new task.

On first launch, the plugin copies the installed Harness Standard mode through the public Agent Preset API and appends its governance tools. Shell, file operations, skills, goals, plans, subagents, and workflow primitives therefore follow the installed Harness version rather than a frozen source copy.

Stage ownership

Stage	Owner	Result
Intake	Zhongshu	Understand the original request, classify its scale, and ask only blocking questions.
Requirements & draft	Zhongshu	Write decision-level requirements and a solution draft without prescribing function-level patches.
Independent review	Menxia	Validate scope, risks, acceptance criteria, and produce the final executable specification.
Countersignature	Zhongshu + Menxia	Agree on the same scale and specification; remand only concrete unresolved issues.
Approval	User	Approve, remand with feedback, or cancel before any execution department is created.
Execution planning	Shangshu	Write 05-phased-development.md, scan every ministry domain, record assignments and omissions, and order dependencies.
Ministry execution	Selected ministries	Produce bounded code, configuration, documentation, measurements, or independent evidence.
Acceptance	Menxia	Verify the approved specification and phased plan; remand failures to Shangshu.
Reporting	Zhongshu	Write the final report and chronicle from real execution and acceptance evidence.
Closure	User	Optionally request task-specific manual checks, then close, remand, or cancel the case.

Task scale is a soft planning signal, not a hard token ceiling. Small requests should stay compact, while difficult work may expand when evidence or implementation requires it. Only explicit user or deployment configuration sets maxTokens.

Six Ministries

Shangshu applies the same matching procedure to all six departments. No ministry is preferred, mandatory, exempt, or used as a generic fallback.

Ministry	Domain	Owns	Does not own
Personnel / 吏部	repository-governance	Repository reconnaissance, module ownership, task decomposition, dependencies, and handoff order	Product implementation or test approval
Revenue / 户部	data-dependencies	Data and state models, migrations, dependency resources, performance impact, and related implementation	Unrelated product features or final acceptance
Rites / 礼部	interfaces-documentation	API/UI contracts, compatibility, accessibility, documentation, user experience, and related implementation	Unrelated infrastructure or final acceptance
War / 兵部	application-code	Product behavior, core application code, refactoring, and code migration	Self-approval or default build/release work
Justice / 刑部	quality-security	Independent testing, reproduction, security and permission review, and regression verification	Implementing the feature currently under independent review
Works / 工部	infrastructure-release	Build systems, development tooling, infrastructure, integration, packaging, deployment, and release	Generic product implementation or replacing independent verification

Shangshu is not a seventh implementation agent. It owns scheduling, dependency coordination, evidence collection, and phase progression. Every ministry is either assigned concrete work or receives a specific omission reason. For code-changing phases, every implementation assignment must be covered by an independent Justice verification dependency.

Runtime guarantees

The plugin enforces these rules in code:

• The root coordinator may create only the Three Departments.
• Only Shangshu may create the Six Ministries.
• Zhongshu, Menxia, and the Six Ministries cannot delegate further.
• Shangshu must register a structured phase plan before dispatching ministries.
• Every assignment references a matching department, role, reasoning effort, deliverable, verification method, and dependency set.
• Failed dependencies do not unlock downstream assignments.
• A successful approval result and a subsequent user-approval: passed milestone are both required before Shangshu can be created.
• tang_submit_final_report requires a successful menxia-acceptance: passed milestone.
• Built-in closure decisions and duplicate verification options are filtered safely so a completed run is not failed by redundant model output.
• The plugin uses public Harness extension points and does not depend on private experimental/agent-team packages.

Model routing

The organization view can set provider, model, and reasoning effort for Zhongshu, Menxia, and Shangshu. Settings are stored in the Harness Settings namespace tang-governance and applied through the public request-routing waterfall.

The Six Ministries never choose independent models. They inherit Shangshu's current provider, model, and explicit maxTokens; Shangshu selects task-appropriate reasoning effort for each registered assignment. Unsupported reasoning levels fall back to the model's declared default instead of failing the dispatch.

Optional deployment defaults can be added to .agent-presets/tang/agent.cordis.yml under Harness Home:

- id: tang-governance-tool
  name: 'dsh-tang-governance/tool'
  config:
    autoDispatch: true
    subagentProvider: spawn
    offices:
      zhongshu:
        provider: deepseek-official
        model: deepseek-v4
        reasoningEffort: high
        maxTokens: 16000
      menxia:
        provider: deepseek-official
        model: deepseek-v4
        maxTokens: 16000
      shangshu:
        provider: deepseek-official
        model: deepseek-v4

autoDispatch defaults to true. When disabled, the first request is no longer forcibly dispatched before the coordinator's first model call.

Case dossier

Each case uses the following durable layout:

.tang/
  config.json
  cases/<case-id>/
    01-requirements.md
    02-draft-solution.md
    03-review.md
    04-spec.md
    05-phased-development.md
    06-final-report.md
    07-chronicle.md

The phased plan records objectives, changed surfaces, boundaries, dependencies, ministry deliverables, verification, risks, checkpoints, and rollback. Function bodies and exact patches remain implementation decisions for the selected ministry.

三省六部治理插件

三省六部治理插件是面向 DeepSeek Harness 的独立 npm Bundle，不修改 Harness 源码。

它把一条开发需求组织成可审计的智能体协作流程：需求澄清、独立审议、用户审批、按职责执行、最终验收、结案汇报与用户确认。关键边界由运行时校验，不只依赖提示词约束。

以唐代三省六部制度为灵感，为现代 AI Agent 软件交付提供清晰的职责分离与治理机制。

核心特性

• 按量级受理：中书省只判断任务量级，避免简单需求运行冗长流程。
• 起草前澄清：需求存在阻塞性歧义时，先通过原生选择界面询问用户，再继续起草。
• 独立审议与会签：门下省独立审查规格，并可针对具体问题封驳。
• 明确的用户门禁：批准前不能进入执行，终验和用户确认前不能结案。
• 六部统一扫描：尚书省按相同规则扫描六个职责域，仅调度能产生实际贡献的部门。
• 运行时职责约束：派发层级、部门角色、依赖、独立验证、审批与结案均由代码校验。
• 可视化执行：响应式架构图、可折叠阶段时间线、部门记录、实时状态和 Token 统计集中展示。
• 稳定模型继承：三省可分别路由模型，六部统一继承尚书省的 provider 和 model，再按任务调整思考等级。
• 持久化案卷：每个任务在 .tang/cases/<case-id>/ 下留下结构化文档。
• 可恢复叫停：用户可随时叫停任务，同时保留已经完成的产物与证据。

安装

环境要求：

• Node.js ^22.19.0 || >=24
• DeepSeek Harness 0.1.1-rc.2 或兼容的 0.1.x 版本

从本地仓库安装：

git clone https://github.com/Ruszero01/dsh-tang-governance.git
cd dsh-tang-governance
pnpm install
pnpm run check
dsh plugin --profile web add link:.
dsh web --no-open

打开 http://127.0.0.1:3080 即可开始使用。

新建任务时选择 三省六部模式。

插件首次启动会通过公开的 Agent Preset API 复制当前 Harness 安装版本的“标准模式”，再附加治理工具。因此 Shell、文件操作、Skills、目标、计划、子 Agent 和工作流等基础能力会跟随 Harness 版本更新，不会锁死在插件开发时的源码副本。

治理流程

用户需求
  ↓
中书省：受理、量级判断、澄清、需求与草案
  ↓
门下省：独立审议与可执行规格
  ↕
中书省 + 门下省会签
  ↓
用户审批门
  ↓
尚书省：阶段计划与六部统一扫描
  ↓
按需启用六部：实现、数据、接口、基础设施或独立验证
  ↓
门下省最终验收
  ↓
中书省最终报告与史官记录
  ↓
用户结案门

阶段	负责人	产出与约束
受理	中书省	理解原始需求、判断量级，只询问阻塞性问题。
需求与草案	中书省	编写决策层需求和方案，不预先规定函数级补丁。
独立审议	门下省	审查范围、风险和验收标准，形成最终可执行规格。
两省会签	中书省、门下省	对同一量级与规格达成一致，只针对实际未决问题封驳。
用户审批	用户	批准、附意见驳回或取消；批准前不创建执行部门。
执行规划	尚书省	编写 05-phased-development.md，扫描六部职责、记录派发与省略理由、排序依赖。
六部执行	按需选择的部门	交付有边界的代码、配置、文档、度量结果或独立证据。
最终验收	门下省	按批准规格和阶段计划验收，失败则退回尚书省。
奏报	中书省	根据真实执行和验收证据编写最终报告与史官记录。
结案	用户	可先要求任务相关的手动检查，再确认、驳回或取消结案。

任务量级是用于精简规划的软性信号，不是固定 Token 上限。简单任务应保持紧凑，复杂任务可根据证据、实现和验证需要扩展。只有用户或部署配置显式设置的 maxTokens 才会成为请求上限。

六部职责

尚书省使用同一匹配流程扫描六部。不存在默认优先、强制启用、豁免或兜底部门。

部门	职责域	负责	不负责
吏部	repository-governance	仓库勘察、模块归属、任务拆分、依赖和交接顺序	产品实现、测试放行
户部	data-dependencies	数据与状态模型、迁移、依赖资源、性能影响及相关实现	无关业务功能、最终验收
礼部	interfaces-documentation	API/UI 契约、兼容性、无障碍、文档、用户体验及相关实现	无关基础设施、最终验收
兵部	application-code	产品功能、核心代码、重构与代码迁移	自我验收、默认承担构建发布
刑部	quality-security	独立测试、缺陷复现、安全权限审计、回归验证	实现自己正在验收的功能
工部	infrastructure-release	构建系统、开发工具、基础设施、集成、打包、部署发布	兜底业务开发、替代刑部验证

尚书省不是第七个实现 Agent，只负责调度、依赖协调、证据收集和阶段推进。每一部都必须被派发实际任务或记录具体省略理由。任何修改代码的阶段，其实现任务都必须由独立的刑部验证任务覆盖。

运行时保证

插件通过代码强制执行以下规则：

• 顶层协调器只能创建三省。
• 只有尚书省可以创建六部。
• 中书省、门下省和六部不能继续派发。
• 尚书省必须先登记结构化阶段计划，再派发六部。
• 每项任务都必须匹配部门、角色、思考等级、交付物、验证方法和依赖。
• 失败的依赖不会解锁后续任务。
• 创建尚书省前，必须同时存在成功的用户审批结果和随后记录的 user-approval: passed 里程碑。
• tang_submit_final_report 只有在 menxia-acceptance: passed 后才能调用。
• 内置结案选项和重复验证选项会被安全过滤，不再因为冗余模型输出让已完成流程显示失败。
• 插件只使用 Harness 公开扩展点，不依赖私有的 experimental/agent-team 包。

模型路由

组织架构图可分别设置中书省、门下省和尚书省的 provider、model 与 reasoning effort。设置保存在 Harness Settings 的 tang-governance 命名空间，并通过公开请求路由生效。

六部不设置独立模型，始终继承尚书省当前的 provider、model 和显式 maxTokens；尚书省只为具体任务选择合适的思考等级。不支持的 reasoning level 会回退到模型声明的默认值，不再导致派发失败。

可在 Harness Home 的 .agent-presets/tang/agent.cordis.yml 中设置部署默认值：

- id: tang-governance-tool
  name: 'dsh-tang-governance/tool'
  config:
    autoDispatch: true
    subagentProvider: spawn
    offices:
      zhongshu:
        provider: deepseek-official
        model: deepseek-v4
        reasoningEffort: high
        maxTokens: 16000
      menxia:
        provider: deepseek-official
        model: deepseek-v4
        maxTokens: 16000
      shangshu:
        provider: deepseek-official
        model: deepseek-v4

autoDispatch 默认为 true。关闭后，运行时不再在协调器第一次模型请求前强制派发原始需求。

案卷目录

每个任务使用以下持久化结构：

.tang/
  config.json
  cases/<case-id>/
    01-requirements.md
    02-draft-solution.md
    03-review.md
    04-spec.md
    05-phased-development.md
    06-final-report.md
    07-chronicle.md

阶段计划记录目标、变更面、边界、依赖、六部交付物、验证、风险、检查点与回滚。函数实现和具体补丁由被选中的执行部门自行决定。
